Ease of Adjustment: Quick-change molds reduce setup time, boosting productivity.
Durability: High-quality steel molds (e.g., 42CrMo) ensure longevity, per ISO 9001 standards.
Tip: Use standard mold systems (e.g., Amada, Wila) for cost-effective replacements and versatility.
Worktable Dimensions
The worktable must support your sheet metal sizes and production demands.
Key Considerations:
Length: Match worktable length (e.g., 2–6 meters) to your largest sheets.
Load Capacity: Ensure support for heavy sheets (e.g., 500–2,000 kg) without deformation.
Back Gauges: Adjustable back gauges improve positioning accuracy for complex bends.
Tip: Choose a worktable slightly larger than current needs for future scalability.

Press brake maintenance and repair should be viewed as an ongoing process rather than a reaction to failure. Proper lubrication, careful hydraulic system management, and regular mechanical inspection form the foundation of reliable machine operation. These practices not only reduce downtime but also help maintain consistent bending accuracy over the machine’s service life.
Choosing the right sheet metal press brake involves weighing hydraulic vs. servo models based on your project needs—material thickness, precision, and production volume. Hydraulic press brakes offer cost-effective power for thick sheets, while servo models excel in precision and energy efficiency for high-tech applications. Consider worktable size, mold compatibility, control systems, maintenance, and manufacturer support to ensure a smart investment. With trends like IoT and hybrid models shaping the future, selecting a press brake that aligns with your goals will boost productivity and quality.
